88 k5 won't crank

  

Lunchbox -> 88 k5 won't crank (11/9/2006 4:36:50 AM)

I can't get my truck to crank. I have checked the fuel pump. I have also reaplaced the fuel filter, Engine Computer, MAP sensor, Fuel Relay, and any blown fused under the dash. The motor cranks right up when I shoot ether into it. What else could it be?

check 2 make sure the injectors r getting a signal. check the union on the grounding side of the wiring harness (about 6 to 10 inches from the injector plugs). i've seen them corrode here and stop the signal from getting through.

Hey, i had the same problem. I checked everything but it ended up being the piece in the distributor cap. I cant remember what it was called but it is a small rectangle piece. Check that and it could fix your problem. My 88 K5 started choking and then it would not start. I checked the same stuff you did and finally figured it out. Hope this helps.
